Dr. Ebraheim’s educational animated video describes differential diagnosis of SI joint pain.
Sacroiliac joint pain can often be mistaken or inappropriately treated for other causes of low back pain.

Piriformis syndrome:
The sciatic nerve is compressed by the piriformis muscle in the buttock. Piriformis syndrome may be associated with lower lumbar radiculopathy similar to spine pathology. It occasionally develops due to blunt trauma to the buttock. Localized buttock pain increased by sitting or driving, tenderness in the sciatic notch.
Lumbosacral disc herniation or bulge:
The disc may move out of place (herniate) or break open (rupture) from injury or strain. Disc herniation of the lumbosacral region could involve the nerve roots causing low back pain. The pain is usually midline and can go down the leg.
Lumbosacral facet syndrome:
The facet provides stability for the spine. These facets contain a joint. That joint may be affected with inflammation or degeneration causing pain that can be mistaken for SI joint pain.
Lumbar radiculopathy:
Major source of back pain. Occurs from inflammation, irritation or impingement of the nerve root. Condition can be confused with SI joint pain.
